Question

The formula below is used to calculate the area of a trapezium.

• a and b represent the length of the two parallel sides.
• h represents the height of the trapezium
Calculate the area of the trapezium at right using the formula below.

Answer 1

14 cm^2

Explanation:

from the data given ,

A = 3 cm

B = 5 cm

H = 4

according to the given formula ,

Area = H / 2 ( A + B )

Substituting values ,

Area = 4/2 * ( 3 + 4 )

Area = 4/2 * ( 7)

Area = 28 / 2

Area = 14
